cannas 2 feet tall in Chicago

My mom gave me 5 tubers of cannas of unknown variety which I planted in May with the rest of my perennials. They just sat there doing nothing until the heat hit early in June. They are still only about 2 feet tall. Is this normal in this zone? When do they flower? Any info would be appreciated.

Mine are about that tall as well. Depending on the variety, they can grow between 2' - 7'or 8' tall in Chicago. Have you seen the ones grown in the middle of Jackson Bd. just east of Michigan? I haven't down that way this year, but in the past, there normally were very tall cannas with striped leaves.

I have seen them in Grant Park and they were tall but I can't remember what month that was. My mom says the ones she gave me get 5-6 ft tall but I thought they would be reaching that height about now. We'll have to wait and see. Thanks.

I'm in Ohio. My canna's are all growing at different rates. I don't know what causes this. The ones on the west side of my garage only get sun after 2, so I understand why they are slower. I have 4 plants in one bed and they are all different size.
Start in the middle of the pic. The big one behind the elephant ear is over 4 feet tall. Move to the right and they all get smaller. They all get the same sun, water, and compost. I have one to the left of the big one that isn't in the pic, and it is also smaller. It's almost like the elephant ear is feeding the canna. I don't believe it's a giant legume.
